A happy Christmas it will be for the the royal newlyweds as Prince William and Kate prepare to celebrate their first holiday season as a married couple.

The Duke and Duchess of Cambridge have decided to pay homage to William's late mother this Christmas, by enjoying the work done by Centrepoint, the organization that works to help homeless youth, ages 16-25. On Dec. 21st, the pair will visit the charity, a favorite of Princess Diana's, in South London to take part in a healthy cooking session , attend a performance from the winner of a Centrepoint's Got Talent show, and catch a group session of the charity's "Workwise" program.

Sounds like a lovely day! There will be some who are quite close to their age, so perhaps will give the royal couple some perspective and motivate Kate to starting thinking about what charities she wants to attached her name to.

As for the actual days of Christmas, the couple will spend it together at the Queen's home, Sandringham, with the rest of the royals.

"My metabolism actually changed like crazy this year. I have Hashimoto's disease. It's a thyroid disease, and it's now been two years since taking the medication for it, so for the VS show I didn't want to lose any more weight, I just want to have muscles in the right place, and if my butt can get a little perkier, then that's good."
